One of the things I find interesting is that it won't necessarily be tied just to popos. I believe other distros are looking into it. (Can't find references now)

If anyone is interested in the 'why', here's an old (1 year ago) thread [0] explaining why they are moving away from GTK.

Wow. Iced is also not mature, but being backed by an important project such as Pop OS gives me hope it will stick around.

Maybe it’s time to dive into Rust with Iced, and port over a Qt project I’ve been working on.
